Alps Alpine HSPPAD143A series digital pressure sensor

The HSPPAD143A series digital pressure sensor from Alps Alpine has a waterproof design for barometer and water depth measurement systems. Barometric and water pressure is detected by a MEMS sensor element using a piezoresistive bridge circuit formed on the silicon diaphragm. The sensor element is connected to an Application Specific Integration Circuit (ASIC) for signal conditioning which has 17-bit Analogue to Digital Converter (ADC) and temperature compensation capability. In addition to the ASIC output compensating pressure values, the HSPPAD143A supports averaging and filtering for lower noise, and FIFO function. The I2C interface is prepared for communication.

3M has presented New 3M™ 100G QSFP28 Direct Attach Copper Cable Assemblies, 9Q Series are passive copper cable assemblies which utilize 3M Twin Axial Cable technology to create a highly-flexible, foldable, high-performance solution.
